Specification of Letters Patent. Patented Dec. 141i, 11915;

Application filed January 21, 1915. Serial No. 3,502.

To all whom it may concern Be it known that 1, FRANK FOLEY, a citizen ofthe United States, and a resident of Mayview, (Gillett post-otfice,) inthe county of Arkansas and State of Arkansas, have made certain new anduseful Improvements in Pumps, of which the following is a specification.

My invention is an improvement in pumps, and the invention has for itsobject to provide a pump having a double piston or plunger together withmechanism for operating the pistons or plungers in opposite directions,and wherein a particular form of piston or plunger is provided,oli'ering'a minimum resistance to the up'flow of the water on thedownward stroke of the piston and a maximum of lifting power on theupstroke.

In the drawings: Figure 1 is a side view of the improved pump with partsin section, Fig. 2 is a partial section showing the guide mechanism,Fig. 8is a top plan view partly in section of the block to which theplunger rods are connected, Fig. 45 is a top plan view of one oftheplungers, Fig. 5 is a side view of the same, Fig. 6 is a bottom planview of one of the plungers, and Fig. 7 is a vertical section of thesaid plunger.

The embodiment of the invention shown in the drawings comprises a pumpconsisting of a cylinder 1 having an outlet pipe 2 near its top, forpermitting the discharge of the water raised and a pair of pistons orplungers 3 and t are arranged within the cylinder, the said pistonsbeing mounted to move in opposite directions and the rod 5 of the piston3 is hollow or tubular to permit the passage of the rod 6 of the plunger4. The operating mechanism for the plungers or pistons consists of astandard 7 having journaled thereon walking beams 8 and 9, the beamsbeing journaled intermediate their ends, the beam 8 at the top of thestandard and the beam 9 near the top but spaced apart from the beam 8 insuch manner that the The standard 7 is secured to a suitable base 10,the standard having laterally extending lugs 11 resting upon the baseand secured thereto by bolts and nuts 12.

ri'suitable motor (not shown) is provided for operating the pump and themotor is connected to a pulley 18 suitably mounted adjacent to thestandard by means of a belt 1 1. The pulley 13 is secured to a shaft 15journaled in the bearing brackets 16 at the opposite end of the basefrom the cylinder and on the opposite side of the standard 7, eachbracket having laterally extending lugs 17 resting on the base andsecured thereto by bolts and nuts 18.

The shaft 15 is provided at each end with i a crank arm 19, the armsbeing secured to the shaft by keys 20 and the arms extend in oppositedirections, as shown. Each arm is connected to a walking beam by meansofa link 21 and 21 respectively, the link 21 being connected to the beam8'wliile the link 21 is connected to the beam 9. It will be evident thatwhen the shaft is rotated the walkbeam is connected to a piston orplunger the pistons will be reciprocated. Since the crank arms 19 extendin opposite directions the walking beams will. be oscillated in op- .ingbeams will be vibrated and since each posite directions. The pumpcylinder 1 eX tends above the base 10 and each walking beam 8 and 9 isin fact composed of two levers spaced apart from each other and rigldlyconnected.

As shown 1n Fig. 2 each of the levers constituting the beams 8 or 9 asthe case may I be is connected at the end remote from the shaft 15 withone end of a link 22, the other end of the link having an opening forreceiving one of the journal pins 23 of a connecting block connected tothe adjacent plunger rod. This block is sectional, each journal pin 23being threaded into the socket of a sectional bearing 24. The sectionsof the bearing embrace the upper threaded ends of the rod 5 or 6, as thecase may be, and the sections are clamped together on the rod by boltsand nuts 40.

Above and below the bearing sections,

nuts 41 are threaded onto the rods, and itlink 22, the links beingarranged at the outer sides of the sockets of the bearingsections 24:and then through a collar 12, and a flange wheel 4-3 is journaled on theouter end of each journal pin. The collars 42 act as spacing members tospace the wheels 13 apart from the links 22, and these wheels arearranged wlth the flanges outward, as

shown more particularly in Fig. 2. Each wheel 42 moves between themembers of'a palr of spaced guide bars 44, .a pa1r; .'of gu de barsbeing arranged at each side of the cylinder and extending outwardly fromthe base 10. The bars are rigidly connected in any preferred manner andthe inner members of the pairs, that is the bars adjacent to thestandard 7, are braced against the standard by upper and lower braces45.

Each brace has its ends bent laterally as shown at 46 and fittingagainst the adjacent bar or standard and the angular portions aresecured to the bars or the standards in any suitable manner. The flangesof the wheels 43 prevent longitudinal movement of the journal pins 23,thus holding the connecting blocks which are in effect cross heads to arigid up and down movement. With this arrangement there is no lateralplay of the plunger rods at their upper ends, and the plunger rods andplungers are constrained to a true vertical movement.

The plungers 3 and 4 are similar, differ ing only in that the upperplunger has an opening at its top and that the rod connected thereto istubular. Each plunger is coneshaped and they are arranged in thecylinder with thelr bases downward. The outer wall of the plunger isstepped, as shown in Figs 4 to 7 inclusive, and each piston consists ofbars 25 secured to the rod 5 or 6, as the case may be, in spacedrelation and 'at right angles of 90 with respect to each other. The barsextend downwardl and outwardly, the upper end of each bar being beveledas shown at 26 to fit against the periphery of the adjacent rod, and theouter side edge of each bar is provided at spaced intervals withvertical faces 27, the bottom of one face being connected with the topof the preceding face by an inclined face 27. The vertical faces 27 andthe inclined faces 27*" of the bars are in register and a cylindricalring 28 is secured to the bars at each series of vertical faces. Eachseries of inclined faces of the bars forms a. support for a series ofvalves 29, each valve being curved transversely to fit against the facesand having its side edges shaped to fit against the side edges of theadjacent valves and the said valves close against the inclined faces ofthe bars. Each valve is hinged to the next lower ring 28, and the endsof the valves are beveled, as shown at 30 at each end, to fit againstthe upper edge of the next lower ring 28 and to fit against the outerface or periphery of the next upper ring 28. a

"A series of hinge leaves 31 is connected With each ring 28 except thelowermost and each valve is provided with a hinge leaf 32 at its center,the leaf being connected to thecadjacent leaf 31. The hinge leaves areconnected by pintles 33 and a spring 34 is secured to each leaf 31 atone end, the free end of the spring beingspacedoutwardly from the outerface of the adjacent leaf an upper portion inclined inwardly slightly,

the arrangement being such that the valves cannot open into verticalposition as indicated in dotted lines in Fig. 7. The lowermost ring 28has its lower edge beveled on the inner surface thereof, as shown at 36,and the outer surface is provided with an annular groove 35 forreceiving a packing ring 37. The valves 29 at the lowermost rings arehinged to the upper edge thereof directly, the hinge leaf 32 of the saidvalves being pivoted to the ring instead of to an other hinge leaf. Thesprings 34 are also secured to the upper edge of the ring at this pointto leave the periphery of the ring uuobstructed.

In operation, when the crank shaft 15 is rotated the walking beams willbe oscillated in opposite directions to cause the plungers or pistons 3and 4 to be simultaneously reciprocated in opposite directions, onepiston making the up stroke when the other makes the down stroke. Aseach piston moves downwardly the valves 29 thereof are moved upward bythe water which passes freely between the rings 28 and through theopenings between the rings. The rings having their wide dimensionvertical offer but slight resistance to the passage of the water. On theup stroke of the piston the valves close against the inclined faces ofthe arms and the water above the piston is lifted with the piston.

The springs 34 limit the opening movement of the valves to a position alittle less than vertical, so that on the up stroke of he piston theaction of the water will swing the said valves inwardly to closedposition. The plunger rod 6 of the lower piston passes through thetubular rod 5 of the upper piston and since the two rods are held to arigid up and down movement there can be no interference between them.

I claim:
